Description

Ignition coils are essential for creating the spark that fires your V-Twin engine. Over time, heat and vibration degrade the internal windings, leading to misfires, weak power delivery, or total failure. Since Hyosung no longer makes the original coils for these early EFI models, we offer a choice: a reliable aftermarket option or a premium Japanese-made unit with superior internal quality control, justifying the price difference. It is an essential performance upgrade for longevity.

💎 Choose Your Performance Level

From reliable aftermarket to high-spec Japan quality, select the option that best suits your budget and performance expectations.

Aftermarket Option Cost-effective, OEM-spec performance.	Japan-Made Option Superior internal quality & longevity.
Fixes Misfires Restores consistent spark timing.	Easy Swap Matches existing connectors.
